/* AegisAI marketing site — shared styles
 * Self-contained, no build step. Drop into Hostinger as-is.
 *
 * v2: GODMODE polish pass.
 *   - equal-height cards via flex column
 *   - responsive table collapse at <720px
 *   - pipeline grid retuned (number column tight against text)
 *   - dark-section accent corrected for contrast
 *   - kicker-center helper class (drops the no-op inline style)
 *   - section anchor scroll-margin-top so #ids don't slip under sticky nav
 *   - hero h1 cap bumped; tighter line-height on huge sizes
 *   - footer brand-dot uses lighter accent on dark background
 *   - .problem-grid as a real class with its own breakpoint
 *   - subtle dividers, tighter spacing rhythm in dense sections
